LAMPPP (Linux Apache MySQL PHP/Python/Perl) was recently deemed the most
secure open source software package by a government-backed
study.

/In the analysis, more than 17.5 million lines of code from 32
open-source projects were scanned. On average, 0.434 bugs per 1,000
lines of code were found, Coverity said. The LAMP stack, however,
'showed significantly better software quality," with an average of
0.29 defects per 1,000 lines of code, the technology company said./
